HARRY S. ROBINSON, OF MEADVILLE, PENNSYLVANIA.

BICYCLE-TRAINER.

SPECIFICATION forming part of Letters Patent No. 562,198, dated June 16,1896. Application filed December 2, 1895. Serial No. 570,812. (Nomodel.)

To all whom it may concern:

Be it known that I, HARRY S. ROBINSON, a citizen of the United States,and a resident of Meadville, in the county of Crawford and State ofPennsylvania, have invented a certain new and useful Improvement inExercising-Machines, of which the following is a description.

My invention has relation to exercising-m achines, and my object is toprovide a device of this character which will be cheap to manufactureand durable in use.

In the accompanying illustrations, forming part of this specification,Figure 1 is a side elevation of my invention. Fig. 2 is an end elevationthereof, and Fig. 3 a plan view of my invention.

Referring to the drawings, 1 indicates a base-piece, to which aresecured ,in any suitable manner two uprights 2, having a shaft 3journaled therein. Mounted on said shaft 3 is a fly-Wheel 4, havingattached to it a sprocket-wheel 5. 6 indicates a band-brake wheel alsosecured to the shaft 3. Also secured to the base-piece 1 is a standard7, hav-- in g a shaft 8 j ournaled therein, and a sprocket-wheel 9mounted on said shaft. 10 indicates pedals of the usual constructionsecured to said shaft 8 in any desired manner.

A saddle 11 and handle-bars 12 are slidably secured to the upright 7,and are adapted to be adjusted as desired by means of the setscrew 13. Adrive chain 14 connects the sprocket-wheel 9 to the sprocket-whee15.Secured to a rod underneath the band-brake wheel 6 is a band-brake 15,to whose end is attached a rod 16, for a purpose to be hereinafterdescribed. Passing through an opening in the upright 7 is arod 17, oneof whose ends is screw-threaded, as at 18, and provided with anadjusting thumb-screw 19.

20 indicates a spring-scale to whose ends are secured the looseextremities of the rods 16 and 17.

An adjusting-plate 18 is secured to the base 1, and is so arranged thatthe upright 7 may be either moved to or from the fly-wheel as desired.

A cyclometer 21 is arranged at one side of the upright 2, while at theside of the flywheel and attached to the axle 3 is suitably arranged alarge wall-dial 22, having a pointer 23 thereon, which is so arranged asto indicate the number of miles made by the rider.

The operation of my trainer is simple. The rider first adjusts theband-brake to any desired resistance by means of the thumb-screw 19, andtakes his position in the saddle with his hands on the handle-bars andfeet on the pedals, the distance which he travels being indicated by thedial.

The gear of the device may be increased or lessened as desired by meansof the adjusting-rod 17.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

A training-machine comprising a base having secured thereto an uprightadapted to be moved either toward or from the fly-Wheel, a shaftjournaled in said upright, a separate wheel mounted on said shaft havingpedalcranks secured thereto said upright having an adjustable saddle andhandle-bar, standards having mounted therein a fly-wheel,sprocket-wheel, and a band-brake and adjusting means for increasing ordecreasing the resisting power of said band-brake consisting of a springindicator-scale, having one end thereof secured to the band-brake andits other end secured to a rod passing through the upright and meanscomprising a set-screw on said rod for adjusting the tension of thespring, as set forth.

In testimony whereof I hereunto affiX- my signature in the presence oftwo witnesses.

H. S. ROBINSON.
